Benefits of technology

The present invention provides a system and method for determining the path length of a device traveling through a body lumen to a specific location. This is done by comparing the raw path length of the device with the path length of the device traveling through the entire body lumen. The ratio between the two path lengths, along with the pre-selected length of the body lumen, is used to determine the true path length through the body lumen to the specific location. The system includes an in-vivo device, a location detection system, and a path-length detection unit. This technology helps to accurately determine the path of a device in the body.

Abstract

A system and method for determining the path length through a body lumen, for example to a specified location, is described. A location detection system may identify the location in space of an in-vivo device over time. A path-length detection unit may use data from the location detection system to determine a path traveled by an in-vivo device. A site of interest along that path may be identified. The distance of the site of interest from at least one end point of a body lumen may be determined.

Description

FIELD OF THE INVENTION[0001]The present invention relates to an in-vivo device traveling through a body lumen, and in particular to a system and method to determine the path length or distance through a body lumen to a specified location.BACKGROUND OF THE INVENTION[0002]The gastrointestinal (GI) tract may typically be a convoluted long tube that folds many times to fit inside the abdomen, proceeding through the esophagus, stomach, small intestine, and large intestine. Autonomous in-vivo devices, for example, ingestible devices that may move through the GI tact, and that may collect data and transmit the data to a receiver system, are known in the art. Such devices may be used to examine areas that may otherwise be difficult to access with non-autonomous devices such as for example, endoscopes, colonscopes, gastroscopes, enteroscopes, laparoscopes, catheters, etc.[0003]During examination of a patient with an autonomous device, a physician may identify one or more sites of interest A ...
